Product details
Overview
NL37WZ14MU3TCG from onsemi is a triple Schmitt-trigger inverter IC operating from 1.65 V to 5.5 V, delivering 2.6 ns typical propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and overvoltage-tolerant inputs/outputs up to 5.5 V. It serves as a noise-immune signal conditioning and waveform shaping element in low-voltage digital interface circuits.
For engineers reviewing the NL37WZ14MU3TCG datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.25–1.7 V), input threshold symmetry, tri-state compatibility, IOFF partial power-down support, and US8 package thermal resistance (250 °C/W).
Technical Context
The NL37WZ14MU3TCG implements three independent Schmitt-trigger inverters in a single US8 package, each with asymmetric input thresholds (VT+ and VT−) enabling robust noise rejection on slow or noisy signals. Its IOFF feature disables I/O leakage when VCC = 0 V, supporting live-insertion and partial power-down systems.
It operates across −55 °C to +125 °C, supports 15 pF load capacitance with sub-5 ns propagation delay at 3.3 V and 5.0 V, and maintains rail-to-rail output swing under ±24 mA sink/source at 3.0 V - all while consuming <10 µA quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters |
| tPD (typ) | 2.6 ns at VCC = 5 V - ensures minimal timing skew in high-speed clock/data path conditioning |
| VH (Hysteresis) | 0.25–1.7 V depending on VCC - provides configurable noise margin for reliable edge detection on degraded signals |
| IOH/IOL | ±24 mA at 3.0 V - drives multiple standard CMOS loads or small capacitive buses directly |
| IOFF Support | Active when VCC = 0 V - prevents back-powering and signal contention during hot-swap or power-gating sequences |
| CIN/COUT | 2.5 pF each - minimizes loading on upstream drivers and preserves signal integrity in dense routing |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments |
Pinout & Package
Supplied in the US8 (Case 493) surface-mount package - 2.1 mm × 2.0 mm footprint, 0.5 mm pitch, 0.55 mm nominal height, JEDEC-compliant, MSL Level 1, Pb-free/RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Inverter 1 Input | Schmitt-trigger input with hysteresis; accepts 0–5.5 V regardless of VCC level |
| 2 (Y3) | Inverter 3 Output | CMOS-compatible output; actively driven high/low or high-impedance when tri-stated |
| 3 (A2) | Inverter 2 Input | Independent Schmitt input; electrically isolated from A1/A3 except via shared VCC/GND |
| 4 (GND) | Ground Reference | Primary return path for all three inverters; must be low-impedance for noise immunity |
| 5 (Y2) | Inverter 2 Output | Output with same drive strength and voltage specs as Y1/Y3; supports bus termination |
| 6 (A3) | Inverter 3 Input | Third Schmitt input; identical threshold and hysteresis behavior to A1 and A2 |
| 7 (Y1) | Inverter 1 Output | Primary output used for clock inversion or signal cleanup; matches Y2/Y3 timing and drive |
| 8 (VCC) | Supply Voltage | Single positive supply for all three channels; powers internal bias circuitry and output stages |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.25–1.7 V hysteresis to reject noise on slow-rising/falling signals (e.g., mechanical switch debouncing) |
| Overvoltage-tolerant I/O | Accepts inputs up to 5.5 V even when VCC = 1.65 V - eliminates external clamping diodes in mixed-voltage systems |
| IOFF partial power-down | Blocks >99% I/O leakage when VCC = 0 V - enables safe insertion into powered-backplane systems |
| Low-capacitance I/O | 2.5 pF input/output capacitance - reduces dynamic loading and preserves rise/fall times in high-frequency paths |
| AEC-Q100 qualified variant | NL37WZ14USG−Q meets automotive stress testing requirements - suitable for body control and infotainment subsystems |
Applications
| Industrial Sensor Interface | Automotive Body Control |
|---|---|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, potentiometer) before ADC sampling or microcontroller GPIO capture. IC Role / Device Role / Timing Role: Schmitt-trigger inverter acts as a clean zero-crossing detector and noise filter for slow-moving DC-biased signals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC14APWR | 6-channel, 3.3 V only (1.65–3.6 V), no IOFF, 3.7 ns tPD at 3.3 V | Lacks overvoltage tolerance and partial power-down; requires strict 3.3 V domain isolation | Select when higher channel count is needed and VCC is fixed at 3.3 V with no hot-swap requirement |
| MC74VHC14DT | 6-channel, 2–5.5 V, no IOFF, 7.5 ns tPD at 5 V, higher CIN (4.5 pF) | Slower propagation, higher input capacitance, no AEC-Q100 qualification | Choose for cost-sensitive industrial boards where timing slack exists and automotive compliance is not required |
Compared with SN74LVC14APWR and MC74VHC14DT, the NL37WZ14MU3TCG uniquely combines triple-channel Schmitt inversion, 1.65–5.5 V operation, IOFF, and 5.5 V overvoltage tolerance - making it optimal for mixed-voltage, hot-pluggable, or automotive-grade signal conditioning where reliability and design margin are critical.

FAQ
What is the maximum input voltage the NL37WZ14MU3TCG can tolerate?
The NL37WZ14MU3TCG supports DC input voltages up to 5.5 V regardless of VCC level - including when VCC is as low as 1.65 V. This overvoltage tolerance eliminates the need for external clamping diodes in mixed-voltage systems and protects against transient overshoot on signal lines.
Does the NL37WZ14MU3TCG support partial power-down operation?
Yes, the NL37WZ14MU3TCG features IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. This allows safe insertion into powered-backplane systems and prevents back-powering of downstream logic, making it suitable for hot-swap and modular system architectures.
What is the typical propagation delay of the NL37WZ14MU3TCG at 3.3 V?
At VCC = 3.3 V with a 15 pF load, the NL37WZ14MU3TCG delivers a typical propagation delay (tPLH/tPHL) of 2.8 ns. This value is confirmed in the AC Electrical Characteristics table under "3.3 ± 0.3 V" test conditions and reflects consistent performance across temperature and process variation.
Is the NL37WZ14MU3TCG qualified for automotive applications?
The NL37WZ14MU3TCG itself is not marked with the −Q suffix; however, its automotive-qualified counterpart NL37WZ14USG−Q is AEC-Q100 Grade 1 qualified and PPAP capable. The NL37WZ14MU3TCG shares identical electrical and thermal specifications but is intended for commercial/industrial use.
What package type does the NL37WZ14MU3TCG use, and what are its key mechanical attributes?
The NL37WZ14MU3TCG uses the US8 package (Case 493): a 2.1 mm × 2.0 mm, 8-pin, 0.5 mm pitch, leadless surface-mount package with MSL Level 1 moisture sensitivity and RoHS-compliant Pb-free finish. Its thermal resistance is 250 °C/W in still air, supporting compact thermal design in high-density PCB layouts.
